COUPLING- SPEGIFIGATION forming part of Letters Patent No. '780,0'?5,dated January 17, 1905.

Application filed June 23, 1904- Serial No. 213,851.

To (LZZ whmn 112'; may concern:

Be it known that we, J AMIGS Tim is and JAMEs O. TIMMs, residents ofColumbus, in the county of Franklin and State of Ohio, have inventedcertain new and useful Improvements in Con plings; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to an improvement in couplings, and moreparticularly to an improvement upon the construction disclosed in ourapplication for patent filed March 3, 1904-, Serial No. 196,402, theobject of the invention being to provide an improved double-endedreversible knuckle with an elongated opening or slot at its center andprovide a reversible filler-block to close a portion of said opening andprovide an opening or hearing for the pivot-pin at either end of saidelongated opening, according to the position of the knuckle.

With this object in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswilllbe more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in horizontal sectionof a coupling, illustrating our improvements. Fig. 2 is a view of theknuckle removed. Fig. 3 is a detail view of the filler-block, and Fig. iis a view illustrating a modification.

1 represents the coupling-head, and 2 our improved double-endedreversible knuckle, which is locked in its closed position by a slidingblock 3 or other form of locking device. The knuckle 2 at its center isprovided with an elongated slot or opening 4,, whose walls may have thegeneral compound curvature shown in Figs. 1, 2, and 3, or the walls ofsaid opening may be parallel, forming a slot or opening of generaloblong formation, as Shown in Fig. 4. 5 represents a filler-block whichis of a size and shape tofill one end of said slot or opening 4 andforming a bearing in the other end of said opening of just the propersize to receive the pivot-pin 6 and permit free pivotal movement of theknuckle. When the knuckle is to be reversed in the head, thisliller-block 5 is reversed in the opening 4, and it will be observedthat there is never but a single opening in the knuckle, and thatopening is just large enough to receive the pivot-pin. The filler-blockadds strength to the knuckle and as itis readily reversible provides, ineffect, two pivotal points of the knuckle without unduly weakening thesame.

Slight changes might be made in the general form and arrangement or theparts described without departing from our invention, and hence we donot restrict ourselves to the precise details set forth, but considerourselves at liberty to make such slight changes and alterations asfairly fall within the spirit and scope of our invention.

Having fully described our invention, what we claim as new, and desireto secure by Let ters Patent, is-

1. The combination with a coupling-head, of a double-ended. reversibleknuckle having an elongated opening in its central portion, a pivot-pinin said head adapted to pass through said opening in the knuckle, and afiller-block adapted to lit into either end of said opening in theknuckle and form a hearing at the other end for the pivot-pin.

2. The combination with adouble-ended reversible knuckle having anelongated opening in its central portion, of a filler-block adapted tofit either end of said opening and provide a circular opening at eitherend to receive the pivot-pin of the coupling.

3. The combination with a double-ended rcversible knuckle having anelongated opening in its central portion, the walls of said. openinghaving general compound curvature, and a filler-block adapted to fiteither end of said opening and provide a circular pivot-pin-receivingopening at either end thereof.

In testimony whereof we have signed this specification in the presenceof two subscrib ing witnesses.
